It is narrated from a Companion (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: "Shall I not tell you about the people of Paradise? Every weak person who is dominated and subdued. Shall I not tell you about the people of Hell? Every ill-tempered person who is spiteful and arrogant."
